<P>PROBLEM TO BE SOLVED: To improve operability in an input device. <P>SOLUTION: A first button 61 and a second button 62 are placed between a keyboard and a pad part 63. This allows a user to operate the first button 61 and the second button 62 with a finger (a thumb, for example) moving a little while operating the keyboard with both hands placed at a home position. Therefore, the user can operate the first button 61 and the second button 62 without largely moving both hands from the home position; that is, the first button 61 and the second button 62 can be operated without interrupting input operation using the keyboard. <P>COPYRIGHT: (C)2012,JPO&INPIT |
